If a muscle is stretched until the zone of overlap between actin and myosin filaments disappears, the muscle can no longer generate force effectively. This is because the cross-bridges formed between these filaments are essential for contraction; without overlap, there are insufficient binding sites for muscle contraction to occur. As a result, the muscle may become weak or unable to contract entirely, leading to a loss of functional strength. This phenomenon is critical in understanding muscle physiology and the limits of muscle stretching.
What else can I help you with?
When a muscle pulls what happens?
you have then stretched your tendon / muscle beyond the normal range .
What happens to muscle force production when the muscle is too short?
Force produced is reduced, when the muscle is over-stretched or under-stretched it is weaker. Most muscles will produce max force at roughly 90 degrees.
What kind of injury happens if a muscle is stretched too far?
boo boo strain
The myotatic reflex is provoked by activation of What in a stretched muscle?
The myotatic reflex is provoked by activation of muscle spindles in a stretched muscle. These muscle spindles are sensory receptors that detect changes in muscle length and help regulate muscle contraction and body position. When a muscle is stretched, the muscle spindles send signals to the spinal cord, leading to a reflex contraction to prevent overstretching.
What tissue can contract and be stretched but not expand?
muscle
When a muscle contracts what does it pull on?
A muscle pull happens when muscles are overworked or over stretched
What are the injuries found in a muscle strain?
A strain is a torn or stretched muscle or tendon.
This area disappears in a fully contracted muscle?
H zone
When the frequency of stimulation of a muscle is great enough?
wave summation results and muscle twitches overlap.
What is the zone of overlap?
The zone of overlap is the point where actin myofilaments overlay the myosin myofilaments as it (actin) gets pulled towards the m-line (mid-point of sarcomere). The zone of overlap increases during muscle contraction, resulting in the shortening of the muscle.
A strain is an injury in which a muscle?
Over stretched or torn
What injury occurs when a muscle is over stretched?
CRAMPS
